REED FOR LOOMS.

I SPECIFICATION forming part of Letters Patent No. 457,409, dated August11, 1891.

' Appncaion inea nach 14, 1891. serai 110.385,021. (No modem To all whomit may concern,.-

Be it known that'I, CLARENCE S. SrRow- BRIDGE, of Hamilton, in thecounty of Madison and State of New York, have invented certain new anduseful Improvements in Reeds for Looms; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to 1omake and use the same, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which form part of thisspecification.

My invention relates to improvements in reeds for looms, and is moreparticularly adapted for usein looms for weaving wire.

In the drawings which accompany and form part of this specification, andin which similar figures of reference refer to corresponding 2o parts inthe several figures, Figure l shows a reed removed from the loom. Fig. 2shows a longitudinal cross-section of the reed shown in Fig. l. Fig. 3shows a longitudinal crosssection of a reed, taken as Fig. 2 is taken,with the dents of the reed arranged in a slightlydifferent manner. Fig.4 shows a longitudinal section of areed, taken as Fig. 3 is taken, withmodified form of dents.

The reed l is constructed in the ordinary 3o manner, except that it isprovided with dents 2, having a convex surface on one side and a concavesurface on the otherand provided with rounded edges. The warpthreadspassing through this reed will be engaged at two points on one side byone of the dents and at one point between the other two points on theopposite side of the thread by the next adjacent dent. The thickness ofthe dents is, preferably, uniform throughout their whole 4o width, whichleaves a passage of uniform width between the dents across the entirewidth of the dent, which passage-way in width is equal to the distanceapart at which the dents are set, so that aknot in the warp wouldreadily pass the reed and yet the warp-threads be constantly engaged oneither side, and thereby always held exactly in the same position withreference to each other. The relative relation of the distance betweenthe 5o dents and the curve of the dents and the `thread will be engagedat three points, as before stated-namely, at each edge of the reed andat points on a line lengthwise in the center of the reed.

In Fig. 3 is shown an arrangement of reeds which accomplish, in the samemanner, the same results heretofore described. This reed (shown in Fig.4L) might be used when the number of threads to be used in the reed are6o few and somewhat far apart.

In Fig. 4 is shown a modified form of construction provided withalternate double-convex dent l0 and double-concave dent IO", which willengage the threads of the warp, as before set forth; but I deem theconstruction shown in Fig. 3 preferable.

What I claim as new, and desire to secure by Letters Patent, is-.

I. The combination, in a reed, of dents 7o having concave surfaces onthe one side and convex surfaces on the other, the convexsurface beingpresented to the concave surface of the next adjacent dent,substantially as set forth. 7 5

2. In a reed for a weaving-loom, the combination of dents having roundededges and a convex surface on the one side and a concave surface on theother, substantially as set forth. 8o

3. 'l`he.'co1nbination, in a reed, of dents curved transversely, withthe front and rear edges of the dentadapted to bear against one side ofa warp-thread` and the middle portion of the opposite side ot' the dent85 adapted to bear against the adjacent warpthread, substantially as setforth.

4. The combination, in a reed, of .a dent having a concave surface and adent having a convex surface presented to the concave 9o surface of theother dent, whereby a thread passing between the dents is engaged at twopoints on one side and at one point intermediate the two points on theopposite side, substantially as set forth. 95

In witness whereof I have affixed my signature in presence of twowitnesses.
